Cooling agent cycle device for vehicle, has coolers arranged on side of bypass section such that heat radiated from cooling agent in one cooler is smaller than heat in other cooler, where agent flow is branched to upstream side of pump

摘要

The device (10) has coolers (13) arranged on a downstream side of a bypass section (A) such that an amount of heat radiated from a cooling agent in one of the coolers is smaller than the heat in the other cooler. A throttle device (20) decompresses and expands the cooling agent on a downstream side of the former cooler. A suction sided evaporation device (21) evaporates the cooling agent on a downstream side of the throttle device. The cooling agent flow is branched to an upstream side of a nozzle section of an ejector pump.
